What condition is your starter in? 70 amps "should be OK"but I can't remember what it pulls right now.

Factory relay is 60 amp iirc, dunno how much the solenoid actually pulls. Id be a little skeptical of those relays... Might go thru them like candy

my starter is fairly new... i was also wondering there are 2 relays dose one lift the solenoid lever and one drop it? or is it one relay for both jobs? one is small with numbers the other is large and sais hi ram...? dose 1 get replaced or 2?

thanks for the input guys!!

One is the fuel shut off relay, and I want to say the other is the fuel heater relay. Only one needs replaced. Geno's garage has the relay you need wayyyy cheaper than dodge (if they can even get it) and they don't sell it individually.
